Hack is a display oriented dungeons & dragons - like game.
|
|
Both display and command structure resemble rogue.
|
|
(For a game with the same structure but entirely different display -
|
|
a real cave instead of dull rectangles - try Quest)
|
|
|
|
Hack was originally written by Jay Fenlason (at lincolnsudbury:
|
|
29 East St., Sudbury Mass., 01776) with help from
|
|
Kenny Woodland, Mike Thome and Jon Payne.
|
|
Basically it was an implementation of Rogue, however, with 52+ instead of 26
|
|
monster types.
|
|
The current version is more than thrice as large (with such new features as
|
|
the dog, the long worms, the shops, etc.) and almost entirely rewritten
|
|
(only the display routines are the original ones - I must rewrite these
|
|
too one day; especially when you are blind strange things still happen).

objects and monsters.

others are just plain stupid. Additional rumors

are appreciated.)

hack.sh A shell script.

(We have hack.sh in /usr/games/hack and

hack in /usr/games/lib/hackdir/hack and all the other
|
|
hack stuff in /usr/games/lib/hackdir - perhaps this
|
|
will make the script clear.

There is no need for you to use it.)

How to install hack:
|
|
0. Compile the sources. Perhaps you should first look at the file config.h
|
|
and define BSD if you are on a BSDtype system,
|
|
define STUPID if your C-compiler chokes on complicated expressions.
|
|
Make sure schar and uchar represent signed and unsigned types.
|
|
If your C compiler doesnt allow initialization of bit fields
|
|
change Bitfield. When config.h looks reasonable, say 'make'.
|
|
(Perhaps you have to change TERMLIB in the makefile.)
|
|
1. If it didnt exist already, introduce a loginname `play' .
|
|
2. The program hack resides in a directory so that it is executable
|
|
for everybody and is suid play:
|
|
---s--s--x 1 play 206848 Apr 3 00:17 hack
|
|
Perhaps you wish to restrict playing to certain hours, or have games
|
|
running under nice; in that case you might write a program play.c
|
|
such that the program play is suid play and executable for everybody
|
|
while all the games in /usr/games are readable or executable for
|
|
play only; all the program play does is asking for the name of a game,
|
|
checking that time-of-day and system load do not forbid playing,
|
|
and then executing the game. Thus:
|
|
-r-sr-sr-x 1 play 13312 May 24 12:52 play
|
|
---x------ 1 play 206848 Apr 3 00:17 hack
|
|
If you are worried about security you might let play do
|
|
chroot("/usr/games") so that no player can get access to the rest
|
|
of the system via shell escapes and the likes.
|
|
If you #define SECURE in config.h then hack will not setuid(getuid())
|
|
before executing a chdir(). Hack will always do setuid(getuid()) with
|
|
a fork. If you do not define UNIX then hack will not fork.
|
|
3. The rest of the stuff belonging to hack sits in a subdirectory hackdir
|
|
(on our system /usr/games/lib/hackdir) with modes
|
|
drwx------ 3 play 1024 Aug 9 09:03 hackdir
|
|
Here all the temporary files will be created (with names like xlock.17
|
|
or user.5).
|
|
4. If you are not really short on file space, creating a subdirectory
|
|
hackdir/save (modes again drwx------) will enable users to save their
|
|
unfinished games.
|
|
|
|
The program hack is called
|
|
$ hack [-d hackdir] [maxnrofplayers]
|
|
(for playing) or
|
|
$ hack [-d hackdir] -s [listofusers | limit | all]
|
|
(for seeing part of the scorelist).
|
|
The shell file hack (in this kit called hack.sh) takes care of
|
|
calling hack with the right arguments.
